Well, with the one I've got sitting here with caps removed, if that were 
the case, it would be a simple matter to just "peel" the circuit board 
off the keyswitch array. That most definitely ain't happening without 
trashing the switches. Perhaps in another version of the //e keyboard, 
but not the ones I've got. The switches are quite obviously soldered 
down. It's quite evident that the keyboard I've got (and every Apple //e 
keyboard I've ever looked at) was assembled in at least four steps, the 
first two not needing to be in any particular order: 

Step 1: "Stuff" the PC board portion with any discretes, jumpers, and so 
on that are on it, including the cable socket.

Step 2: "Stuff" the metal frame with the key-switches

Step 3: Position the frame full of keyswitches wire leads through the 
pre-drilled holes.

Step 4: Wave-solder (or whatever actual method was used) the whole thing 
together, and trim excess leads.

For the case you're referring to, Step 1 would include stuffing little 
"socket" connections like those used for the power-on lamp to receive 
the leads from the key-switches. In that case, the keyboards would be 
more or less a simple "snap-tite" construction after the soldering was 
finished, and it would be about zero effort to "rip the back off it" 
when you needed to do something with the key-switches themselves.

I *MAY* (Don't hold me to it, but...) be able to get ahold of one or 
two, if it's worth my effort. Let's discuss this further via Email.
